Correct Option (B)
The gilt-edged market refers to the market for government securities. These securities are considered highly secure investments due to the backing of the issuing government, implying a very low risk of default. The term "gilt-edged" historically referred to the gold-leaf edges of such certificates, signifying their premium quality and reliability.
Incorrect Options:
Option (A) Bullion market: This market deals with the trading of physical gold and silver, typically in the form of bars or coins. It is distinct from the market for government securities.
Option (C) Market of guns: This refers to the trade of firearms and related weaponry. It has no association with financial markets or government securities.
Option (D) Market of pure metals: This encompasses the trading of various refined metals, including industrial metals and precious metals. While gold and silver are pure metals, this option is broader than the specific "bullion market" and distinct from the "gilt-edged market."
